    Abstract
  • It is a hot topic if the Jurassic coal can generate oil in the Ordos Basin.The adsorbed hydrocarbons amount in the Jurassic coal is 50-80 kg/t but the productivity of coal is only 6.02-70.7kg/t based on the experimental result.If produced oil is less than adsorbed oil in coal,the coal cannot be an effective source rock of oil.On the other hand,comparing to the coal of large and medium sized oilfields in the world,the Jurassic coal in the Ordos Basin is characterized by lower abundance,unfavorable type and lower maturity,which indicates uneffective source rocks.In terms of characteristics of biomarker,the Jurassic oil is not generated by coal in the Ordos Basin.Therefore,the Jurassic coal in the basin can not generate sufficient oil to form a commercial oilfield.
